So i was playing Tntwars : building cannons and a player lvl 1 start placing blocks in front of the cannon of my cannon blocking the shot which result in the death of my cannon and spamming the lever of my cannon destroying it

And many times he said that I/other players was griefing and/or trolling to get us report

The name of the player is MinSoft

Quite entertaining Video tho.

Blocking the TNT with Stone Bricks did cause your cannon to get blown up. 

That player should get banned alright. He knows what he did.
